SZPUR ROLL FOB SHINGLE MACHINES.

To all whom it mar/y concern: 7

Be it known that I, LEONARD H. CRAW- FORD, a citizen of the United States, residin at Inglewood, in the county of King an State of Washington, have invented a new and useful Spur Roll for Shingle Machines, of which the following is a specification.

This invention relates to improvements in spur rolls for shingle machines and the primary object of the invention is to provide a spur roll with a plurality of dies having raised numbers, letters or other characters thereon to designate each particular machine and arranged in such manner as to insure the spall or residual segment of the shingleblock receiving an impression from said raised characters thus providing a tally by means of which said spalls may be identified with said particular machine and its operator.- 1 I The ultimate object of the invention is to provide means which will prevent the waste I of materialjcaused by workmen striving to cut a record number of shingles when employed on piece work. Rather than utilize the material to the best advantage of the employer, it is the common practice for shingle machine operators to discard the spalls when they become small and irregular in shape to the extent of retarding theirprogress. It is needless to state that an operator will refrain from such wasteful practice when he is aware that his mark is being stamped on each spall as evidence of his wastefulness.

With the above and other objects in view which will appear as the description .proceeds, the invention consists of the novel construction, adaptation, arrangement and combination of parts hereinafter described and claimed.

These objects are accomplished by devices illustrated in the accompanying drawings, wherein:

Figure 1 is view in longitudinal elevaa shinglemachine, and showinga spall in its normal operative position therein;

Referring to the drawings throughout in which like reference numerals designate like parts, the numeral 5 designates the cylindrical body portion of a spurroll on. which two of them are in the same longitudinal I alignment. The object of this arrangement is to obviate any tendency which said dies might have in'interfering with the grip of said teeth on the-shingle block shouldthey be placed in alignment, and also to insure that one or more of said characters will impress itself upon the spall as more fully hereinafter described.

It will likewise be noted that the outer surfaces of the bases 7 are slightly short of the outer points of the teeth 6 in radial length and that the die characters 8 project slightly outside of the outer points of said teeth, as clearly'indicated by projected clotted lines in Fig. 2 of the drawings. Al'- though not limiting myself to this particu lar arrangement, the purpose of same is to insure a substantial contact of said teeth and'die characters with the shingle block without interference by said bases.

In Fig. 6 of the drawings I haveshown, in part, a top plan view of an upright shingle machine which is the present predominat :ing type of machine in use, and, in which the numeral 9 designates the framework, the mo numeral 10 designates the circular saw, the numeral 11 indicates part of a shingle block, and the numeral 12 indicates the upper one of. the spur rolls shown in dotted lines. As

is well understood, in this type of machine there are two spur rolls horizontally arranged, one above the other, and said shingle block is placed between with its grain in an upright position and with the teeth of said spur rolls in engagement respectively with no its upper and lower surface ends.

As the shingle block 11, is drawn between the spur rolls 12 to engage the saw 10 where it is sawed into shingles, the latter part of said block is known as a spall. It said spall happens to be of irregular shape or contains knots .or other defects which would necessitate its being shifted in order to utilize all the material to the best advantage,

, gered longitudinal relation, the purpose be ingto place said characters on the roll in such manner that one or more of same will be sure to. impress itself' upon the spall 11 regardless of its shape. It will be understood that each particular machine and its operator is known by the particular character used on the spur rolls of that machine and that each machine in a mill is designated by a different set of characters. As hereinbei'ore stated, the operator will discontinue the wasteful practice of throwing away valuable spallmaterial when he is aware that his indentification character is stamped thereon and will inevitably be discovered in the spall pile iii not before.

lVhile l prefer to show the dies as an in tegral part of the spur roll, I do not limit myself to this particular construction, it

ravesas being obvious that same might be sprung, screwed, or otherwise fastened to said spur roll. It may be remarked that my device is equally applicable to the horizontal type of shingle machine in which the spur rolls are arranged vertically and the shingle block is placed between same with its grain in a hori zontal position.

Having thus described my invention, it being understood that such changes may be resorted to as are within the spirit and scope of the invention, what I claim and desire to secure by Letters Patent is 1. An article of manufacture comprising a spur roll body portion, spur teeth arranged" in spaced apart ring formation on said body portion, dies between saidteeth. disposed around said body portion, and said dies being positioned in different planes both longit-udinal and vertical with respect to the axis of said body portion.

2. An article of manufacture comprising a spur roll body portion, spur teeth arranged in spaced apart ring formation on said body portion, die bases between said teeth, said teeth projecting outside the peripheral line of said bases, die characters on said bases said characters projecting outside the peripheral line of said teeth, and said die bases and characters disposed in longitudinal staggered relation around said spur roll.
